I don't remember, Actually I am busy to send all documents
through courier today , so that they get it in next week.
Which courier u hve used??
Very astonishing on part of CIC.In my view send the docs ASAP .Moreover to be on the safe side send copies of all emails send by you to them and also copies of any automated replies from their office, in case if you receive them(automated reply is received in most of the cases no matter you receive their actual reply) that would be of great help.
Moreover you can send an email to Minister Jason Kenny @
jason.kenney @ parl.gc.ca
Minister @ cic.gc.ca.
Request him in a very polite and humble manner to look into your case and accept your docs as you have been waiting for this time from the past 7 years.
will pray for you and good luck!
